And should you pva seal all romos or just bathrooms and kitchens?

No rooms at all! Never put PVA on plaster before painting; it's far
worse than not treating it at all. It seals the plaster, but makes a
nice non-stick layer which the paint will subsequently peel right
off. Use cheap diluted-down emulsion.

David, you should have typed that in capital letters! DON'T PUT PVA ON
BARE PLASTER IF YOU INTEND TO PAINT OVER IT!!!!!!!!!


Hmmm - I've nearly always done it, and never had any problems. I've
occasionally used thinned emulsion instead, and that's worked fine too.
Once her ladyship changed the plan and I had to emulsion over sizing, and
that worked OK as well.

Seems to me that the key is to use a very light, thin penetrating
application, rather than slather on so much paint/pva/size/sealant so it
skins.
